Apparently in cases of Tourettic OCD, people get the urge to do OCD-like compulsions, but the urge arises from a physical feeling; not a fear or obsessive thought. According to the article:
“TOCD sufferers report discomforting sensory experiences such as physical discomfort in body parts including hands, eyes, stomach, etc., or a diffuse psychological distress or tension, for example, ‘in my head’ or ‘in my mind.'”
What to make of all this? Will there one day be Chronic Obsessive Transient Tourettic Compulsive ADHADD — with a dash of Autism?
